it's really hard to overcome your panic inside you

I used to know how to swim. But now when I go swimming, I fear the water. It might be another kind of acrophobia since I'm especially afraid of deep water. My friend Amstar wanted me to go swimming in the deep end with her today. I felt reluctant to go, but since she's my best friend and I trust her, I went to the deep end and felt my panic coming by...It's a horrible experience. Water came in my mouth and I was deadly nervous.
It just reminded me of a theory we cover during our class in communication. The theory is called Uncertainty Reduction Theory. It assumes that when people are uncertain about something during their communication, they tend to reduce the uncertainty and the top solution is information-seeking. But there will be some cases that people refuse to reduce the uncertainty or the uncertainty increases against their will. I think my swimming can be categorized into the refusal of uncertainty reduction which is clearly coming from my strong feeling of saying no.
If it's an extreme situation which may threaten people's lives or other significant influences, they may not want to discover the uncertainty and reduce it. They may just keep it as what I did for swimming. Always swimming in the shallow end. Afterall, life is the most precious to me.
